Myopia: Induced, normal and clinical

Abstract
A review is given of lid-suture myopia in monkeys, of the natural lower field myopia in the pigeon eye, and of myopias in chick eyes produced by visual occluders. The ametropias produced by ophthalmic lenses, and the pharmacology of experimental myopia, are reviewed. Human studies are reviewed which can be taken as models of the experimental myopias. Two theories of myopic growth are outlined and evaluated.
